I read a very interesting book a few years back:
The Church Impotent: The Feminization of Christianity by Leon Podleshttp://www.amazon.com/Church-Impoten.../dp/1890626198
I'm Orthodox, and I remember one bit from the book that really stuck with me. It's something along the lines that Russian Orthodoxy is the only Church that writes music for basso profoundo (sp?).
I will say that "Orthodoxy is not for wusses." Our spiritual disciplines alone cause a great deal of people to go "What??" Going essentially vegan during about half the year leaves a lot of people with their jaws on the floor (I've witnessed this myself." The long services.
We're not afraid to talk about sin, unlike some Christian bodies today.
Definitely agree with the lack of sentimentality.
